Unit 3 Section Ⅰ（课件PPT）-【精讲精练】2026-2027学年高中英语选择性必修第一册（北师大版）

该高中英语课件围绕“环境保护”主题，系统梳理听力核心词汇（如wildlife, endangered species）、短语（die out, be in danger）及策略指导（逻辑推理与态度推断），通过“词汇储备—策略应用—核心知识—巩固练习”的递进支架，帮助学生构建主题语言知识网络。 其亮点在于融合语言能力与思维品质培养，听力策略结合高考真题实例（如通过语音语调推断Sophie的担忧情绪），核心词汇配备“即学活用”练习（如destroy的语法填空与语境应用），强化知识迁移。同时渗透文化意识（环境保护观念），学生能提升语言运用与问题解决能力，教师可依托结构化内容高效开展教学。

A．Talkative and friendly. B．Quite and unfriendly. C．Talkative and unfriendly. Text W：Linda is very quiet，but her husband talks too much. M：You are right，and he isn't very friendly. 【分析】　根据听力内容中的Linda，quiet，but her husband等， 我们很容易看出Linda的丈夫不安静(talkative)；从男子话中的not very friendly我们不难推出unfriendly。故此题选C。 　(2024·浙江1月卷)How is Sophie feeling now? A．Confused.　　　 B．Worried. C．Disappointed. Text M：All well, Sophie? W：Hmm...not great.I'm just so down with writing this report. M：Are you almost done with it?

B．Indifferent. C．Against. Text ... W：I heard even the most famous newspapers are starting to go bankrupt. M: Maybe paper books will disappear someday，too.People are starting to read electronic books. W：I'm pro the idea of “e-books replacing paper books”， but I just wish they could make the experience of reading an e-book more comfortable to our eyes. 【分析】　根据听力内容中I'm pro(赞成，支持)the...paper books可以推出女子的态度还是“赞成的”(supportive)，故此题选A。 [重点词汇] 1．destroy vt.破坏；毁掉了 destroy sth　摧毁某物 destroy sb　毁掉某人 destruction n.　摧毁；破坏 destructive adj.　有破坏性的 Nearly everything in the city was destroyed. 城市里的一切几乎都被毁掉了。 [即学活用] 单句语法填空/完成句子 ①After such ___________(destroy), many problems in resettlement often arise. ②Those anticancer drugs are effective, but also ___________ (destroy) to white blood cells. ③________________________(大桥被毁坏) so we couldn't get across the river. 2．switch vi.& vt.转换；改变 switch(sth)(over)(from sth)to sth　将……转换成…… switch sth between　 A and B　在A和B之间转换 switch sth over/around/round　将……换掉 switch sth (with sth/sb)　将……对调/与……换班 switch sth on/off　开/关(电灯、机器等) Then I get up，go downstairs and switch on the TV in the living room. 然后我起床，下楼，打开起居室里的电视。 One of my classmates asked me if I would mind switching seats with her. 我的一个同学问我是否介意和她交换座位。 [即学活用] 单句语法填空/完成语段 ①There are so many buttons and ________(switch) that I am not sure which one I should turn on. ②The middle-aged sales manager determined to give up his promotion and ___________________________(改变他的生活方式).He __________________________________________(把工作从销售部换到) the design department，and since then he has lived a life more comfortably.
